Technical FAQs 4

What is the European energy storage inventory?

A new interactive platform delivers real-time clean energy storage insights as Europe shifts toward sustainable energy sources. Energy storage helps to balance supply and demand. The European Energy Storage Inventory is the first of its kind at European level to show all forms of clean energy storage solutions.

How does energy storage work in the EU?

The main energy storage method in the EU is by far 'pumped storage hydropower', which works by pumping water into reservoirs when there is an electricity surplus in the grid - for example on a sunny or windy day - and releasing it when more energy is needed.

Which countries have the most storage facilities in Europe?

Europe’s current total operational power is around 66 GW, and planned projects mean this might double to 132 GW by 2035. According to findings from the inventory, Germany, Italy and Spain have the main relevant storage facilities among the member States.

What is the EU energy technology inventory?

The inventory provides policymakers with up-to-date data to shape energy security strategies and the EU's revised Strategic Energy Technology Plan (SET Plan). The inventory also has the potential to feed into the Clean Energy Technology Observatory, ensuring that storage trends are considered in EU-wide energy technology assessments.
